Trevor spent half of his allowance going to the movies. He washed the family car and earned seven dollars. What is his weekly allowance if he ended with sixteen dollars ?
Let X = Trevor's weekly allowance. If Trevor spent half of his allowance for movies that means, he spent 1/2X. If he washed the car and made seven dollars, and ended with sixteen dollars total, that means we get the formula: 1/2X +7 = 16. We can subtract 7 from both sides to get (1/2x + 7) -7 = 16 -7 1/2x = 9 Multiply both sides by 2 to remove the coefficient from x. (1/2x)2 = 9(2) x = 9 * 2 x = 18
